A handful of OS X users on Reddit are reporting a weird bug that makes Launchpad simultaneously unusable and rather beautiful.
According to Cult of Mac, the problem is a result of OS X using an incorrect core filter built into the OS when it throws up Launchpad:
[S]omehow Launchpad is applying the crystallize effect when it should be using blur. It’s a bit whacky and goes away after a bit, but it sure is spectacular.
It’s weird, sure, but at least it looks kinda cool. Has this happened to you? [Reddit via Cult of Mac via Ubergizmo]
